FUJIKURA FRM2 Solvent-Compatible External Adjustment Relief Valve

• Solvent-compatible relief valve: The FRM2 can be considered for solvent, chemical, and special liquid relief applications based on fluid and material compatibility.
• Reduced outside-leak risk: Compared with the FRM1 Series, the FRM2 is designed to reduce the risk of outside leakage.
• External cracking pressure adjustment: Cracking pressure can be adjusted externally and is set before shipment according to the specified pressure.
• Inline high-flow design: The inline structure routes relieved fluid through the outlet piping, supporting high-flow relief and recovery layouts.
• Seal material options: FKM is the standard seal material, while EPDM and Kalrez can be considered for chemical, solvent, and corrosive-fluid applications.

Q1: What is the FUJIKURA FRM2 Series?
A: The FRM2 Series is a solvent-compatible external cracking pressure adjustment relief valve that allows the cracking pressure to be adjusted externally and relieves pressure when line pressure reaches the set value.

Q2: What fluids can the FRM2 Series handle?
A: The FRM2 Series supports gas and liquid that do not corrode wetted parts. Solvent, chemical, and special-liquid applications should be evaluated based on material compatibility.

Q3: What is the difference between FRM2 and FRM1?
A: FRM2 is designed to reduce outside-leak risk and support solvent applications. FRM1 can include pull ring or toggle lever manual release options.

Q4: Is FRM2 an atmospheric or inline relief valve?
A: FRM2 is an inline relief valve with an Rc1/4 outlet connection, making it suitable for systems where relieved fluid is routed through outlet piping.

Q5: What cracking pressure range is available?
A: The cracking pressure setting range is 50 to 1500kPa and is divided into A, B, and C pressure range codes.

Q6: Can the FRM2 cracking pressure be adjusted by the user?
A: The FRM2 can be adjusted externally, and it is set before shipment according to the specified pressure. Actual adjustment should follow equipment conditions and safety requirements.

Q7: What is the maximum working pressure?
A: The maximum working pressure is 2.0MPa, and the pressure resistance is 3.0MPa.

Q8: What body materials are available?
A: Brass and SCS14, equivalent to SUS316, are available depending on fluid compatibility, corrosion resistance, and operating environment.

Q9: Can a manual release mechanism be added to FRM2?
A: No. FRM2 does not support a manual release mechanism. Use the FRM1 Series if a pull ring or toggle lever is required.

Q10: What applications is the FRM2 Series suitable for?
A: It is suitable for solvent line relief, liquid line relief, chemical-fluid relief, pressure tank control, compressors, compact pressure vessels, gas generators, machine tools, industrial furnaces, medical equipment, and analyzers.
